Dr Stachewicz and Mr Ura propose instead to use a technique called electrospinning. This also involves a hollow needle.

斯塔切薇兹博士和尤拉先生提议使用一种叫做静电纺丝的技术，这也涉及空心针。

As they describe in ACS Nano, Dr Stachewicz and her student Daniel Ura have done it by changing the way the threads are spun, which is cheap.

正如他们在《ACS Nano》杂志中描述的那样，斯塔切薇兹博士和她的学生丹尼尔·尤拉通过改变纺线的方式实现了这一目标，这种方式成本很低。

And then there was the bed, apparently lined with ura sedge from Northeast China, which the locals stuffed into their shoes to stay warm in the cold climate.

然后是床，显然是铺着来自中国东北的乌拉莎草，当地人把它塞进鞋子里以在寒冷的气候中保暖。

Dr Stachewicz and Mr Ura experimented with different potential differences between needle and drum and eventually found one that resulted in meshes able to collect 50% more water than commercial versions, at no extra cost of production.

斯塔切薇兹博士和尤拉先生对针和滚筒之间的不同电势差进行了实验，最终找到了一种能比商业版本多收集50%水的网眼，而且不需要额外的生产成本。
